利用南京地区常见粘性土和蒙脱石含量为95%的膨润土掺合制备膨胀土，通过实验研究蒙脱石掺量与制备的膨胀土的自由膨胀率、膨胀率、试样剪切强度的关系并分析8种土样的黏聚力、内摩擦角随蒙脱石含量的变化关系。最终对实验结果做一些合理的分析，为改良膨胀土提供一些依据。

In this paper, we use common clay in Nanjing area and Bentonite with content of 95% to blend and prepare expansive soil.we study the relationship between montmorillonite content and free expansion,expansion, shear strength of prepared expansive soil through experiments. Analyze soil cohesion, internal friction angle of the eight kinds of soil samples with the variation of the content of montmorillonite.At last we do some reasonable analysis of the experimental results and provide a basis for expansive soil improvement.
